Error in initial loading of the landing page of the "Performance" app

Hi Team,

the client has requested to duplicate the "performance" app and rename it.
When opening the duplicated app, there is initially a page loading error. To be more precise, it seems like the landing page is incorrect. However, the final load eventually directs to the correct page.
I'm sharing a screenshot of the initial page that seems to open.

Has anyone else encountered this issue before?

Thanks in advance,

Vittoria
